Abstract

This chapter discusses a unified and comprehensive theory of the thermoluminescence (TL) dose response of thermoluminescent systems applied to LiF:Mg,Ti. Radiation-induced effects in biological and solid-state systems, especially the effects of ionization density, continue to be of far-reaching implications and intensive investigation. The complexity of the TL mechanism arises in part from the multistage nature of the conversion from the initial energy imparted by the radiation field to the final energy liberated as TL photons. Irradiation of LiF:Mg,Ti induces several radiation-induced centers. It is found that the electron trapping centers (TCs) and the hole trapping recombination luminescence centers responsible for the major dosimetric glow peaks in LiF:Mg,Ti , are spatially correlated. Optical absorption measurements is one of the few direct means of obtaining information concerning the charge trapping nature of the various defect centers participating in the TL mechanism. It is found that optical absorption dose response in LiF:Mg,Ti is far less complex than TL dose response.
